I purchased an MM3 with custom tuning from Ray at DoubleRDiesel (@DoubleRDiesel). I have loved the tuning on the truck since I have installed it. I have a 2012 Ram 2500 Laramie with 68RFE transmission. The tuner has been working great until today when I was leaving work. The tuner worked this morning when I drove to work, but when I was leaving the tuner did not turn on. The light on right of the screen flashed red twice and then green and then red twice again. I looked up on the internet and it said to reformat the SD card. I reformatted the SD card from FAT32 to FAT(Default) and that didn't fix the problem. What do I need to do to fix the problem? Also this question is for Ray. My transmission tuning has been great other than a few small things. It only happens every now and then, but when I come to a stop sometimes my truck kinda lunges forward like the converter is unlocking. Also when I take off slow and don't get up to speed and I have to slow down again it shifts hard like it is going into a low range gear. I got the trans tuning that increased the line pressure from 160 to 170. If anyone could help me with these problems I would greatly appreciate it. Thanks!!
